2. DESCRIPTION
The seating tool is an assembly of an adapter and a
blade.
During seating, the seating tool sits inside the header
housing with the blades engaging the housing floor
and contact shoulders, preventing the contacts from
pushing out of the housing.
3. REQUIREMENTS
3.1. PC Board Support Fixture (Customer Supplied)
A pc board support must be used to provide proper
support for the pc board and to protect the pc board
and header assembly from damage. The board
support fixture must be designed for specific needs
using the following recommendations:
— It should be at least 25.4 mm [1 in.] wider than
the pc board
— It should have a flat surface with a cutout of at
least 28.5 mm [1.12 in.] deep (to allow adequate
clearance for the header assembly)
